9GAG is an online platform and social media website based in Hong Kong, which allows its users to upload and share user-generated content or other content from external social media websites. Since the platform for collections of Internet memes was launched on April 11, 2008, it has grown in popularity across social media such as Facebook, «X», and Instagram.
The website was co-founded in 2008 by a group of five Hong Kongers: University of Hong Kong student Ray Chan, his brother Chris Chan, Derek Chan, Marco Fung, and Brian Yu, with the intention of creating an alternative online platform to email on which users could easily share humorous photos or videos. In a 2012 interview, its CEO Ray Chan declined to explain the origins of the name “9GAG”.
